VE. Bus BMS with Skylla ip44 via Venus GX

If I connect a VE. Bus BMS (connected to Victron Smart LiFePO4) and a Skylla IP44 to a Venus GX, will the BMS be able to control (disconnect/connect) the charger without additional devices (remote disconnect)? Or, must I use the BMS charge disconnect output?

Hi, Paul.

I have exactly the same components and would also like to know if it is possible. Please let me know if it works for you - I have not installed mine yet as I am still researching the possibilities.

How will you connect the VE.Bus BMS to the Venus GX? Is it possible to use the Multiplus/Quattro connection for this? The manuals are not very clear on this.

I chose the Skylla-IP44 charger for its variable voltage input. This way I can plug my boat into shore power anywhere in the world. On the charging side I also have solar panels and alternators that need to be controlled.

Paul,

I just went through the whole process and found that you HAVE to control the IP44 with the "charge disconnect" of the BMS - there's no other way to disconnect the IP44.

The Venus GX will not control the IP44.

Hi, Daniel.

You say to test these functions. How do you actually test them? You have to mimic an over-voltage to make sure the BMS shuts off the Skylla but how do you do this in practice?
